ROAD-GRADER.

Application filed August 13, 1909.

Specification of Letters Patent.

Serial No. 512,677.

To all 'whom t may concern.'

Be it known that I, JOSEPH PENDLETON LUrEs, a citizen of the UnitedStates, and a resident of Buffalo, in the county of Dallas and State ofMissouri, have invented a new and Improved Road-Grader, of which thefollowing is a full, clear, and exact description.

The invention is an improvement in road graders or drags, and has inview a device of this character in which each scraper takes care of itsown dirt from the time it leaves the ditch until it is discharged at thecenter of the grade, thus avoiding the danger of clogging, and makingthe device 'easy of operation and light o f draft. This I accomplish byconstructing the grader with a front and rear scraper spaced apart andrigidly connected together, with the front scraper relatively longerthan the rear scraper and each having a downwardly and inwardly-inclineddischarge end, the opposite ends of the Scrapers being preferablydownwardly and inwardly inclined, to clear the curb or dirt at the sideof the road, and arranged, when the scraper is thrown at the angle oftravel, on a line substantially parallel to the road.

Reference is to be had to the accompanying drawings forming a part ofthis speciication, in which similar characters of reference indicatecorresponding parts in both views.

Figure l is a perspective view of a road grader or drag constructed inaccordance with my invention; and Fig. 2 is a crosssection through thescrapers,

In the construction of the road grader, I employ a front scraper 5 and arear scraper 6, of substantial height and rigidly connected together inspaced relation by bars 7. The bars are arranged near the top of thescrapers, through which they pass, and are extended to the rear of thescraper 6, where they serve to fasten the upper ends of braces 8connected to and reinforcing the rear scraper, similar braces 8aextending between the connecting bars 7 and the front scraper to performa like function. The Scrapers instead of being arranged exactlyvertical, incline downwardly and forwardly, as shown in Fig. 2, in orderto add further strength to the grader and decrease the vibration. Thefront scraper is substantially longer than the rear scraper, and bothhave downwardly and inwardly-inclined discharge ends 5a and 621respectively, with the discharge end of the front scraper extendingbeyond the discharge end of the rear scraper, and the opposite ends ofthe scraper preferably incliiiing downwardly and outwardly as iiidicatedat 5b and 6b, in order to clear the curb or dirt at the side of theroad, and arranged on a line approximately parallel to the road when thegrader is thrown at the proper angle for operation. The scrapers haveattached to their front faces at their lower edges, cutting blades 9 and9a respectively, the cutting blades having the bottom cutting edges, asshown in Fig. 2.

To the top edges of the scrapers are secured metal rails l0 and 10a,with the rail l() of the front scraper extending beyond its dischargeend, at which point it is connected with one end of a tree ll by a staychain or cable 12, by which this end of the grader is controlled. Thetop rail l0 is further connected with the tree 1l at the center or oneside thereof by a draft chain or cable 13, the latter being adapted tobe engaged in any one of a number of hooks 14 arranged along the lengthof the tree. The tree 1l in the embodiment of the invention shown is adoubletree of a four-horse evener, which will in practice be required indrawing the grader. I-Iowever, this is not essential to the invention.

The connecting bars 7 adjacent to the ends 5b and 6b of the Scraperscarry plat-- forms l5 and l5Z1 respectively, the platforms adjoining theiear sides of the scrapers,

In the operation of the grader, the draft chain and stay chain areadjusted to cause the grader to travel at the required angle to the lineof draft. The grader is then drawn along the road, with the inner endsof the cutting blades on a line with the gutter, in which position ofthe grader the inclined ends 5b and 6D of the Scrapers clear the curb ordirt at the side of the road. The dirt as it is cut off and evened vbythe cutting blades, travels outwardly and is discharged toward thecenter of the road under the downwardly and inwardly inclined ends `5ELand 6a of the scrapers, 'the dirt passing under the inclined end 55L ofthe front scraper being deposited outwardly beyond the path of thedischarge end 6a of the scraper 6, whereby the scraper 6 will not againtake up this dirt and clog the drag in its travel. In this way eachscraper takes care o1 its own dirt from the time it leaves the ditchuntil it is discharged toward the center of the road.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

l. The combination in a road grader, of front and rear Scrapers spacedapart and rigidly connected together, each scraper having a downwardlyvand inwardly-inclined discharge end, with the discharge end of the frontscraper extending outwardly beyond the discharge end of the rearscraper.

The combination in a road grader, of front and rear Scrapers spacedapart and rigidly connected together, a draft tree, a stay'- cable bywhich the outer end of the machine `is controlled, extending between theouter end of the front scraper and the adjacent end of the tree, and adrag cable connected to the opposite ends of the front scraper at apoint intermediate the length ot the tree.

The combination in a road grader, of front and rear Scrapers spacedapart and rigidly connected together, with the front scraper relativelylonger than the rear scraper, each scraper having a downwardly andinwardly-inclined discharge end, with the opposite ends of the Scrapersarranged on a line approximately parallel to the line of draft.

4. The combination in a road grader, of front and rear scrapers spacedapart and rigidly connected together, with the front scraper relativelylonger than the rear scraper, each scraper having a downwardly andinwardly-inclined discharge end, with the opposite ends of the Scrapersinclining downwardly and outwardly.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
